Orthopaedic Technologist Certified Fracture Classification and Management Flashcards

Which term best describes a fracture where one bone end is driven into the other by compressive force?

Answer: Impacted fracture

An impacted fracture occurs when compressive force drives one bone fragment into the other, often resulting in a relatively stable fracture pattern.

The Ottawa Ankle Rules are a clinical decision tool used primarily to determine the need for which diagnostic study?

Answer: Ankle radiographs

The Ottawa Ankle Rules guide clinicians on whether ankle and foot X-rays are indicated based on specific bony tenderness and ability to weight bear.

A torus (buckle) fracture in a pediatric patient is best characterized by which finding?

Answer: Cortical bulging without complete fracture

A torus fracture causes a buckling or bulging of the cortex at the metaphysis without complete fracture, as the bone compresses under axial load.

When the distal fracture fragment deviates laterally away from the midline, which alignment term applies?

Answer: Valgus

Valgus angulation describes lateral deviation of the distal fragment away from the body midline, while varus refers to medial (inward) deviation.

The Schatzker classification is most commonly applied to fractures of which anatomical location?

Answer: Tibial plateau

The Schatzker classification divides tibial plateau fractures into six types (I–VI) based on fracture pattern, location, and degree of comminution or depression.

Which term describes the fracture malalignment where bone fragments overlap side-by-side rather than end-to-end?

Answer: Bayonet apposition

Bayonet apposition describes fracture fragments lying parallel and overlapping each other side-by-side, causing shortening of the bone segment.
